Looking for a smart watch, happy to pay up to $300-$350. Obviously needs all the health tracking abilities, but also would like it to link well to my phone for notifications etc. I'm not out here running marathons, so I don't need one of the really expensive Garmin watches. Just like tracking the random bike rides/walks and having good health tracking.
LTE ideal but I always have my phone with me anyway so not really required.
For reference I had the Samsung Galaxy Active Watch 2 in the past and really like it, the size suited me well. It just decided to stop working one day and I never replaced it! Bummed I missed out on the recent Galaxy Watch deals!
This will be controversial to some, but there's a postdoctoral scientist who specialises in biological data analysis on YouTube who reviews smart watches called the Quantified Scientist. From the videos I've seen of his, the best smart watch to track health metrics is the Apple Watch.
I'm pretty certain that the latest versions track sleep very well if that's important to you. He compares sleep stage tracking from the devices he tests to an EEG monitor and the latest Apple Watches (including the Ultra) had very high correlation to the EEG device compared to all the other watches he's tested, maybe watch the videos and see for yourself. If you can't afford the latest Apple Watches, the charts he shows in his videos will have other devices that should track health pretty good too. I just took a look at the sleep stage chart for the Series 9 video and Apple Watches seem to perform quite highly regarding sleep tracking.
This is an interesting story about how Apple got into the health-tracking game also.
